. l hicle and the numeral 2, onelof the axles thereof. STER, a citizen of the United States, residlng- In ,constructing my improved spring structure the first unit comprises an ordinary series ofsprings 3 clamped to the axle 2 in the usual manner and being at each end provided with links a by means of which the springs are `linked to the supporting brackets 5 secured to the frame 1.

springs 6 interposed between the springs and the franel and provided at eachy end with links 7 the pinsl 8 at one end ofsuch formed in brackets 10 secured to the frame" 70 1.. Clamped to the springs 6 are another series of springs 11 disposed in a reverse position and provided at their ends with links 12 flexibly connecting them to a spring 13 clamped to the springs' 3. y

The third unit of my spring structure in- .cludes 'the shock absorbing spring '14 which is substantially Straight and isr clamped between the springs 6, and 11 and is provided- '89 connected, as at 16,'and connected as at 1T with the frame 1. In practice, With ordinary trafiic vibrations, the frame of' the `vehicle l rides solely on the springs 3, the

pins 8 on the links 7 under vsuch conditions movable'vertically through the slots 9 leaveing the springs 6 and 11 inactive. W ith nheavier jolts and jars however, the pins S would come to a stop at the upper ends of` the slots 9 .and then the springs 6 and 11 would' come into action to compensate for such heavy j olts and jars. VVith-any down `Ward movement of the vehicle frame 1, the

links 15 would break at their pivotal points 16 and fold toward eachother, but with the rebound they Would straighten out and pull againstthe spring 14' which would thus com- ,pensate for such rebound and .act as a shock' absorber. f

From the' lforegoing 'description it can 190 readily be ascertained thatv by having the unitary spring structure described, each'unit erforms a compensating action against the joltsandjars 1n `successive order according' 'i to theextent of the same so that each unit 105 Y ymay be mafie extremely -flexible in itself to` allow of easy riding qualities'for the vehicle,

whereas the .entire structure prevents any excessive joltmg of such-vehicle. i

be readily seen that I have produced such a f device as substantially fulfils the objects of the invention as set forth herein.

' Vhile this specification sets iforth in detail the present and preferred construction of. the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the nspirit of the invention as defined by the appended claims. 104 Having thus described my invention what I claim' as new and useful and desire to secure by Letters Patent is zv scribed comprising the combination with a 154 hiele having a frame and axle, of a spring nature interposed between said frame and giXl-e, such structure comprising units, the iitstgunit consisting `of a series 'of springs 'IaInpedto the axle and flexibly' connected with the frame, the second unit comprising .two series of springs clamped together in 'inverted position with respectto each other, one series of the said second unit being flexibly connected with the first unitl and the wfither series ofA the second named unit being iexibly connected with the vehicle and a rebound spring interposed between' the in- `verted springs and. flexibly connected with the. vehicle, as described.

, A vehicle spring of the character described con'iprising the combination with a vehicle having a. frame and axle, of a spring structure lnterposed betweensaid frame and 1. A vehicle spring of the character desuch axle. such s irinfr structure bein(r di- 2'? 23 structure interposed between the frame and" axle, such spring structure beinxg1r divided into units, the Atiret unit comprising a series of springs clamped to the axle and flexibly connected with the frame,l the second unit comprising av series ot' springs connected with the first-named springs and fiexibl'v connected with the frame. the third unit comprising' a rebound spring).r clamped between said second named springs, and a pair of links connected at each end of said rebound spring and to said vehicle, the members of each pair of links being pivotally connected together, as described.

In testimony whereof I aflix my signature in presence'of two witnesses.
